**Approval and Promulgation of Implementation Plans; Texas;**  **Revisions to Voiding of Permits and Extension of Permits** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to approve severable portions of a submittal from the State of Texas, through the Texas Commission on Environmental Quality (TCEQ), on September 25, 2003, to revise the Texas Major and Minor New Source Review (NSR) State Implementation Plan (SIP). Within this SIP submittal, the State repealed a paragraph of the SIP rule pertaining to the Texas Major and Minor NSR SIP and renumbered the SIP rule’s paragraphs. We are proposing to approve the new replacement rule as meeting the Major and Minor NSR SIP requirements for voiding of permits.

We are also proposing to approve the portion of the revision that addresses the recodification of the provision relating to the granting of one 18-month extension of a permit as meeting the Major and Minor NSR SIP requirement for extensions of permits. The revision imposes requirements on permitees, requiring a review of the permit’s underlying permit determinations before this SIP-approved extension can be granted. Finally, the revision provides for a second permit extension if certain conditions are met, including a health effects review. EPA is proposing to approve the new replacement rule for this second permit extension as meeting the Major and Minor NSR and NNSR SIP requirements.

EPA finds that these changes to the Texas SIP comply with the Federal Clean Air Act (the Act or CAA) and EPA regulations, are consistent with EPA policies, and will improve air quality. This action is being proposed under section 110 and parts C and D of the Act.

**SUPPLEMENTARY INFORMATION :**  In the final rules section of this Federal Register , EPA is approving the State’s SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no relevant adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this action, no further activity is contemplated. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of the rule, and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse
comment.

For additional information, see the direct final rule which is located in the rules section of this Federal Register

**Proposed Significant New Use Rule for 1-Propene, 2,3,3,3-tetrafluoro** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing a significant new use rule (SNUR) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified as 1-Propene, 2,3,3,3- tetrafluoro- (CAS No. 754–12–1) which was subject to premanufacture notice (PMN) P–07–601. This proposed rule would require persons who intend to manufacture, import, or process the substance for an activity that is designated as a significant new use to notify EPA at least 90 days before commencing that activity. The required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit the activity before it occurs.
